STANDARD SPECIFICATION FOR RIGID ACRYLONITRILE- BUTADIENE-STYRENE (ABS) PLASTICS
|Publication Date:||26 June 1981|
This specification covers rigid thermoplastic compositions which are made from polymers or blends of polymers, or both, produced from the monomers acrylonitrile, butadiene, and styrene (ABS) or their closely related chemical derivatives and which contain a minimum of 13 % acrylonitrile, 5 % butadiene, and 15 % styrene. ABS plastics may also contain a maximum of 10 % of other monomeric or polymeric components. Other necessary compounding ingredients may also be present. These plastic compositions are suitable for injection or compression molding, calendering, and extrusion.
The values stated in SI units are to be regarded as the standard.
NOTE 1-This specification includes commercially available compounds meeting the composition requirements given herein and only those cell combinations that are applicable thereto. Materials available at the time of publication, listed by their cell classification, can be found in the appendix. Periodic updating of this listing will be at the request of the seller.
For pipe applications, other minimum composition requirements for acrylonitrile, butadiene, and styrene apply. For example, see Specification D 1527.
This specification provides for the division of ABS polymers into groups based on three properties: Izod impact strength, deflection temperature under load, and tensile stress at yield point. These three properties are the most significant in characterizing differences between ABS eompounds.
NOTE 2-The properties included in this specification are those required to identify the types and grades of materials covered. There may be other requiremenfs necessary to identify particular as their inclusion becomes generally desirable and the necessary test data and methods become available.
